AbstractClose multilinear relationship was obtained between the surface global radiation and the cloudiness characterized by the relative brightness in METEOSAT images as well as the solar elevation. The annual variation determined in previous work, in case of the daily average values, can exactly be replaced with the solar elevation investigating hourly sums of the global radiation. The solar energy reaching the surface can easily be estimated by this simple multilinear formula.
